Betty Powers, 69, of Franklin Street, died at a Toledo hospital just hours after the crash.
Authorities had speculated she may have suffered a medical condition prior to the crash. A preliminary autopsy by the Lucas County coroner’s office determined Powers had indeed suffered from a heart disease.
Witnesses said Powers’ vehicle slammed into the back of a stopped car before tearing across a parking lot and slamming into a large oak tree. The vehicle also caught on fire.
Powers was flown by medical helicopter to a Toledo hospital, but she died hours later from her injuries, officials said.
